@YoungJim409 from a few years in the business. investment casting is mainly used for turbine (not compressor) blades and NGV's that have complex geometry, ie. internal cooling channels or cavities. By comparison compressor blades have a (relatively) simple geometry and are not hollow, so machining from solid, be it a rolled bar or a forging, is normally used. Let me just clarify - I do not mean that 17-4PH cannot be cast, but it not economical.

@jarekad Where do you get that idea?

@YoungJim409 this is a compressor blade. these are not investment cast, but machined from solid, pretty much as shown in this video.

@enytned1 This was probably a prototype part or a demo of the machine; production parts like these are investment-cast, finish machined, then most likely x-ray and liquid penetrant NDT before they get shipped out.

I work for GE Canada and is the best job in the world.

i just reallly want to know how people made turbines before the great computerage.... ie; in the sixties already the jets were working with turbines, even the waterdriven powerplants used them... as precise these guys, i can figure out they even x-rayed the machinists too :-)))

make sure they're error fre:-))

yes these pieces are under high pressure and if they fail people might die so everything is triple checked.
